Our data identify four major periods of high sedimentation
rate: (1) during the middle Jurassic with a rate of
4.9 103 km3/Myr, (2) during the CampanianePalaeocene with a
rate of ~3.2 103 km3/Myr, (3) during the middle Eocene with a
rate of ~3.9 103 km3/Myr and (4) during the Miocene with a rate
of ~2.5 103 km3/Myr.
